According to Forrest Fenn, the poem was written by an architect.
Barn built by Rich brothers in 1900 on the family farm
I saw this cool post on ‘poems that look like what they’re about’ and, of course, thought of the Thrill of the Chase treasure poem.
Is the poem a map?
Synchronicity.
Some things are built to last, like the poem—
—or the treasure’s resting spot, good for thousands of years.
Some things come crashing down—
—like your hopes if/when someone else finds the bronze chest.
(Unless you’ve stored your treasures where they will not rust or be stolen.)

I like the satellite dish next to the old stone barn. I think that the poem is a map if you know how to read it. That is not quite as easy as ff might lead us to believe.
Agreed!
